I didn't answer, they left an 8 second message with no audio.

Left no message

Getting calls from this number and on Do Not Call list.

I answered after getting a few calls. Someone saying that they are asking for donations for firefighters. It's a scam. Do not give them any information or money! They said they would mail out information but never asked for an address (not that I would have given it to them). Also kept asking over and over if they could count on my support, I said no, not without information. They wouldn't give me any info on their "charity".

Caller ID said Rockford MI.  I did not answer.  They did not leave a message.
